SuperRare uses Ethereum blockchain smart contracts to record and verify the provenance and ownership history of every digital artwork listed on its marketplace, providing collectors with a tamper-proof authentication record.

Each artwork minted on SuperRare is tokenized on the Ethereum blockchain, embedding permanent metadata on-chain that tracks ownership history and verifies the piece's origin. The platform's co-founder John Crain described this combination of provenance and AI-created art as enabling authentication of 'nearly any piece of art.' This is a blockchain automation function rather than a machine learning AI system, but it intersects with discussions of AI art authentication. Sources do not confirm SuperRare uses machine learning algorithms specifically for authenticity classification; the authentication mechanism is blockchain-based smart contracts.
